This paper describes TerraHidro that is a distributed hydrologic modeling platform. TerraHidro is general purpose water resources system that presents a new concept to represent water flows based on graph structure, in the geographic information system (GIS) context. The drainage extractions and Amazonian basin delimitations using TerraHidro have been compared with ArcGis Hydro Tools regarding ...

A physically-based, distributed-parameter hydrologic model was used to simulate a recent flood event in the city of Hafr Al Batin, Saudi Arabia to gain a better understanding of the runoff generation and spatial distribution of flooding. The city is located in a very arid catchment. Flooding of the city is influenced by the presence of three major tributaries that join the main channel in and a...

Based on more than 4,500 km of new and re-processed multichannel seismic lines, high-resolution seafloor bathymetry, available well data, basement dredge samples, we have re-evaluated the entire stratigraphy tectonic evolution Alboran western Algerian basins. We correlated sediment units deposited since beginning formation different sub-basins, present for first time a coherent large-scale whol...

The main objective of the present study is to investigate the hydrogeology of the Jalakandapuram sub – basin, groundwater potential and quality of groundwater for domestic, industrial and agricultural purposes. Jalakandapuram ( Latitudes 11° 35‟30‟‟N to 11°46‟25‟‟N and Longitudes 77°48‟30‟‟ E to 78°2‟E) Subbasin is one among the four subbasins of the Sarabanga minor basins which comes under the...

Agricultural soils provide ecosystem services, but the removal of natural vegetation reduces water infiltration capacity, increasing surface runoff. Thus, monitoring erosion is critical for sustainable agricultural management. Sediment losses and runoff were evaluated using a simulated rainfall 75 mm/h in areas with crops pastures both Caiabi River Renato sub-basins Teles Pires watershed Mato G...

Selecting the flow accumulation threshold (FAT) plays a central role in extracting drainage networks from Digital Elevation Models (DEMs). This work presents MR-AP (Multiple Regression and Adaptive Power) method for choosing suitable FAT when DEMs. employs 36 sample sub-basins Hubei (China) province. Firstly, topography, normalized difference vegetation index (NDVI), water storage change are us...

Quantitative assessment of the frequency and magnitude drought events plays an important role in preventing disasters ensuring water security river basins. In this paper, we modified a parsimonious two-parameter monthly balance (TPMWB) model by incorporating generalized proportionality hypothesis with precipitation potential evapotranspiration as input variables. The TPMWB was then used to simu...
